取り込み方法

下記のPKGをそのまま取り込む

package com.yanheng.drawgraph.graph

xmlをに追加

※：今回はボタンを押下したら描画開始するイメージです。

<Button
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="グラフ生成する"
    android:layout_margin="30dp"
    />

<com.yanheng.drawgraph.graph.DrawViewDemo
    android:id="@+id/draw_view"
    android:layout_margin="50dp"
    android:layout_width="300dp"
    android:layout_height="200dp"
    android:background="#2260A8FF"
    />

ボタン押下後処理

private void setGraph() {
    createSettingData();
    createGraphData();
    DrawViewDemo drawViewDemo = (DrawViewDemo) findViewById(R.id.draw_view);
    drawViewDemo.setGraphSettingData(graphSettingData);
    drawViewDemo.setGraph1(graphMail);
    drawViewDemo.setGraph2(graphFemail);
    drawViewDemo.invalidate();
}

• X軸、Y軸の設定

  private void createSettingData() {
  graphSettingData = new GraphSettingData();
  graphSettingData.title = "身長グラフ";
  graphSettingData.graphNmae1="男の子";
  graphSettingData.graphNmae2="女の子";
  
  graphSettingData.axisDataX.maxScale = 18f;
  graphSettingData.axisDataX.minScale = 10f;
  graphSettingData.axisDataX.scaleValue = 1f;
  graphSettingData.axisDataX.scaleTitle = "年齢(歳)";
  
  graphSettingData.axisDataY.maxScale = 180f;
  graphSettingData.axisDataY.minScale = 120f;
  graphSettingData.axisDataY.scaleValue = 10f;
  graphSettingData.axisDataY.scaleTitle = "身長(cm)";
  }
  

• グラフ評価の設定上記データを使用する

  private void createGraphData(){
  graphMail.put(10f, 138.9f);
  graphMail.put(11f, 145f);
  graphMail.put(12f, 152.4f);
  graphMail.put(13f, 159.5f);
  graphMail.put(14f, 165.1f);
  graphMail.put(15f, 168.4f);
  graphMail.put(16f, 169.8f);
  graphMail.put(17f, 170.7f);
  
  graphFemail.put(10f, 140.1f);
  graphFemail.put(11f, 146.7f);
  graphFemail.put(12f, 151.9f);
  graphFemail.put(13f, 155f);
  graphFemail.put(14f, 156.5f);
  graphFemail.put(15f, 157.2f);
  graphFemail.put(16f, 157.6f);
  graphFemail.put(17f, 158f);
  }
  

• 描画更新

  drawViewDemo.invalidate();
